As shown in JP-A-54-68882, a punching type manufacturing method for obtaining a bearing seal B by punching the reinforcing material a together with the sealing material b with the press punch 4 at the same time is also carried out. However, when mounting the bearing seal B, as shown in FIG. 4, when the reinforcing ring 2 is placed inside the bearing 1 and fitted in pursuit of rust or hermeticity, the lip portion 5 of the sealing ring 31 is It is pulled according to the reinforcing ring 2 and guided to the inside of the fitting groove 6, and since a direct fitting force is not applied to the lip portion 5,
It was a structure with many mounting defects in which chipping was likely to occur and it was not placed in the correct position.

As shown in FIG. 2, a bearing seal A attached to a bearing 1 and 1'rotating relative to each other to form a hermetic seal, is made of metal. When a sealing material b made of an elastic material is fixed to both surfaces of a reinforcing plate a made of, for example, and then punched by a press punch 4 to obtain a bearing seal A having the sealing rings 31 and 32 and the reinforcing ring 2, As shown in FIG. 1, at least one sealing ring (31 in the figure) is formed with a lip portion 5 whose peripheral edge projects from the peripheral edge of the reinforcing ring 2, and the sealing ring 31 side on which the lip portion 5 is formed is attached to the bearing 1. Place on the outside and seal ring 3 on both sides
It is characterized in that 1 and 32 are compressed and deformed by the press-fitting jig 7 and fitted into the fitting groove 6 of the bearing 1.

プ部５を持つベアリングシールＡを形成する。The present invention has the above-mentioned structure and exhibits the following excellent effects. That is, according to the present invention, a sealing material b made of an elastic material such as synthetic rubber is fixed in advance on both sides of a reinforcing plate a such as a thin plate or a band plate, and this is punched by a press punch 4, and one sealing ring 31 is formed as shown in FIG. A bearing seal A having a lip portion 5 as shown in FIG.

Each of the rings 31 and 32 is sandwiched between the fitting shelf 61 and the press-fitting jig 7 to be compressed and deformed, and the thickness thereof is greatly reduced so that all the members 2 including the lip portion 5 in the fitting groove 6 of the bearing 1. 31 and 32 are forcibly inserted, and when the press-fitting jig 7 is opened here, they are elastically restored and accurately fixed in the fitting groove 6 as shown in FIG.

However, in a normal method, only one sealing ring 31 is covered with the lip. The part 5 cannot be formed, and the other sealing ring 32 may be a partial sealing ring (not shown) corresponding to the fitting shelf 61 portion for the fitting action.

はない。This bearing seal A has a very useful shape in a seal member for a very small portion such as a miniature bearing, and can be mounted in a portion where the fitting groove 6 of the bearing 1 cannot be expected to have high accuracy. And Further, the adjustment of the fixing force can be easily changed by adjusting the thickness and hardness of the sealing rings 31 and 32, and it is not necessary to rely on the increase of the contact area of the fitting shelf 61.

でその密着性さえ良好なものとする。According to the present invention, the bearing seal A is firmly fixed with a high dropout load due to the increase in the mass of the spring back generated by the sealing rings 31, 32, and the solid seal is achieved. I saw a big improvement in sex. Further, the bearing seal A of the present invention not only dramatically improves the moldability, but also eliminates the mounting defect in the fitting work, and the sealing ring 3 and the reinforcing ring 2 do not cause the generation of peeling and peeling. Moreover, since the reinforcing ring 2 is pressed from both sides in the fitting groove 6, its adhesion is good.
